This design-build project will involves the installation of a 1000 square foot locker room inside an existing dam. Features of work include steel structure installation, plumbing, electrical, HVAC systems, and finishes. NCM has subcontracted with two design firms to complete the plans and specifications for the project. Design and substantial completion will occur within a short six month window.

This $2.9 million project involves designing and installing three components- Increase the flow rate of the air stream, increase the cleanliness of the outdoor air drawn into the powerhouse, and achieve more effective pressurization of the powerhouse. Design has begun and the onsite work will start in February 2019.

This is a $4.7 million project that includes removing and installing new low voltage and medium voltage motor control centers and large unwatering & drainage pumps, and installation of an oil water separator system all inside the powerhouse at Lower Monumental Dam.
